Description |
|
Our
Single-mode Couplers have reached the leading edge level
in the world because of its excellent reliability and
high performance. The extremely low Excess loss and PDL
have greatly improved components reliability and
long-time stability. We are taking specific techniques
to handle the empty end so as to eliminate
reverse-directional reflection. Our couplers ensure
above-60dB directivity, and long-time good
stability. | |
